OBJECTIVE: To analyze the effects of exposure to fine particulate matter from burning on hospital admissions due to respiratory diseases in children and the elderly. METHODS: This is an ecological time series study that took place in the city of Cuiaba, Mato Grosso, in Brazil's Amazon Region, in 2005. Information on the daily levels of fine particulate matter PM2.5 was made available by the Brazilian National Institute for Spatial Research. The model included variables related to temperature, relative humidity and adjusts for seasonality and calendar effects. Poisson regression with generalized additive models was used. RESULTS: A 10 µg/m3 increase in the level of exposure to PM2.5 was associated with increases of 9.1%, 9.2% and 12.1% in hospital admissions due to respiratory diseases in children for moving averages of 1, 2 and 5 days, respectively. For the dry season, the level of exposure to particulate matter was associated with increases of 11.4%, 21.6% and 22.0% in hospital admissions in children for moving averages of 1, 5 and 6 days, respectively. No significant link was noticed in the elderly. CONCLUSIONS: The results show the influence of PM2.5 on hospitalizations for respiratory disease in children under 5 in the region studied.
